Be it known that l, Summon W. BoNsALL,

a citizen of the United States, residing at -Rye, in the county of lVcstchcster and State of New York, have invented certain new and useful :lil'lpIOYQlHODlS in Rotary Driers; and Il do hereby declare the follo-ivingto be a full, clear, and exact description of the in vention, such as will enable others skilled in the art .to which it appertains to make and use the same.

The'preseut invention has for its object the provision of cilicient. means whereby various materials may be quickly dried, and.

particularly to means especially suited to the drying of lumber in various forms.

The invention an improvement upon the general type of device set forth in my alpplicat-iou for United Sitates Patent. for improvement in driers, filed November 17th, 1911., Serial No. 660,819.

In a preferred embodiment the invention is shown in the accompanying drawings. wherein Figure 1 shows a vertical sectional view of the device With boards in place onthe right side. Fig. 2 is a plan of the some. viewed from above after removal of the top oil the machine. and 3 as detailed sectional view making, clear the m ans for conveying and removing steam.

The particular form, shape and propor tions shown in the drawings are not essential end are shown iherely by Way of illustration. It is also to be understood that it is not. essential to my invention to employ steam or other heating means.

Upon a base 10 the principal chamber is mounted upon suitable rollers 12 or other non-frictional supports. The chamber is provided with a floor 13 andwalls 14: and, in the particular -form shown is separated into two similar halves by a cross par tition whose ends form scoopsin both horizontal direotions,,which scoops extend beyond the'liniits of the chamber.

'The preferred construction shown in-' volves two suitable bent partitions 15 and 16 placed, back to'back and giving room for the introduction oi the steam pipes herein.- a'tter described. The outer vertical edges of these partitions are bent or curved so as to fornrscoops extending in both directions as viewed vertically. This is ole v'iironi Eig.

The chamber is provided .vT th openings on both Eddchfiust .e'or scoop @l ldltl.

shaped outer edge of the partitions 1'5 and 16. These openings are clearly shown in doors 1?. l8, 15) end 20. whereby the extentof each opening may be accurately deteri'uiued for the purpose hereinafter dcscribed.

Assuming now that the chamber is 1'0- tated, as for instance by the pulley 21 in the direction of the large arrow at the bottom of Fig. 2,-it will be seen that the scoop shaped edge of the partition 16, which is opposite the door 18, Will act to force in- W rd a strong current of air indicated by .70 the small arrows, While the opposite scoopshapedcdgc of the same partition. that is to say the one opposite the door 17, will by its movement create continually a vacuum in front of itself whereby the movement of air is further accelerated. By opening the door 18 to a greater extent. than the door 17, the air Within may be compressed. to such an extent, Within limits, as may be desired. and this operation will be found useful in the drying" of lumber and of other articles wherein the moisture is more or less deeply seated. It. is obvious that the scoop-shaped vertical edges of the partition 15 will have the some ellcct us that of the partition 16, that the air will be forced in through the opening opposite the door 20 and will leave the device opposite the door 19, as indicated by the small arrows. Where puck to be moist. it Will be found wcl to use a heating system of some land in connection Wlll] this device and for this purpose I have construction. The vertical pipe 22 contains two COlllPfllill'ltlllH 9.3 and F24- communicating pt-wmaneutly with the chambers and 96 respectively. within which the entire pipe revolves with the drying chun'ibcr. Steam is introduced into the chamber 25 by the pipe 27 and passes out of the chambc 26' through the pipe 28. All this isshown in Fig. 3. One of the compartments 23 has an extension 29 which leads to a coil 30, in one of the entrance openings While the other compartment- 24: has an extension 31 l fading); to. a similarcoil 32 in the other. entrance opening, the opposite end of which coil is connected by the pipe 33, with one end ot'the coil 30, as shown in Fig. 2. It is obvious that by this means a' circulation of steam is produced through the apparatus, whereby any up n'opriatc manner and :1"
